Hey! I never thought of that. I have the data and there is a monsterous
spike right before shutdown. And that is in a car at only 200 mph and a
short tow line. A bagged stroud chute might work better to relieve some of
the jerk. I would like to see a system that lets the chute blossom right
immediately after deploy then pay out the tow line. Like on a big reel with
a wind up spring or torsion bar...Dave D, are you listening?
